Under https://maps.dwd.de/geoserver/dwd/wms?service=WMS&version=1.1.0&request=GetMap&layers=dwd%3ARX-Produkt&bbox=-523.462%2C-4658.645%2C376.538%2C-3758.645&width=767&height=768&srs=EPSG%3A1000001&format=application/openlayers DWD offers Rain Radar data via openlayers.

I believe this is the relevant code snippet:

     var untiled = new ol.layer.Image({
       source: new ol.source.ImageWMS({
         ratio: 1,
         url: 'https://maps.dwd.de:443/geoserver/dwd/wms',
         params: {'FORMAT': format,
                  'VERSION': '1.1.1',  
               "LAYERS": 'dwd:RX-Produkt',
               "exceptions": 'application/vnd.ogc.se_inimage',
         }
       })
     });
     var tiled = new ol.layer.Tile({
       visible: false,
       source: new ol.source.TileWMS({
         url: 'https://maps.dwd.de:443/geoserver/dwd/wms',
         params: {'FORMAT': format, 
                  'VERSION': '1.1.1',
                  tiled: true,
               "LAYERS": 'dwd:RX-Produkt',
               "exceptions": 'application/vnd.ogc.se_inimage',
            tilesOrigin: -523.462 + "," + -4658.645
         }
       })
     });
     var projection = new ol.proj.Projection({
         code: 'EPSG:1000001',
         units: 'm',
         axisOrientation: 'neu',
         global: false
     });
     var map = new ol.Map({
       controls: ol.control.defaults({
         attribution: false
       }).extend([mousePositionControl]),
       target: 'map',
       layers: [
         untiled,
         tiled
       ],
       view: new ol.View({
          projection: projection
       })
     });

Here is a short demo how to use the DWD rain radar data

This is the code, which needs to be added to app/service/map.js

//=========== DWD SAT Image Overlay
          new TileLayer({
             visible: true,
             source: new TileWMS({
             url: 'https://maps.dwd.de:443/geoserver/dwd/wms',
             params: {'FORMAT': 'image/png',
                   'VERSION': '1.1.1',
                    tiled: true,
                    "LAYERS": 'dwd:SAT_WELT_KOMPOSIT',
                    "exceptions": 'application/vnd.ogc.se_inimage',
                    tilesOrigin: -15.074981 + "," + 34.7373759815055
                    }
             }),
          }),
//=========== DWD Rain Radar Overlay
          new TileLayer({
             visible: true,
             source: new TileWMS({
             url: 'https://maps.dwd.de:443/geoserver/dwd/wms',
             params: {'FORMAT': 'image/png',
                   'VERSION': '1.1.1',
                    tiled: true,
                    "LAYERS": 'dwd:WX-Produkt',
                    "exceptions": 'application/vnd.ogc.se_inimage',
                    tilesOrigin: -15.074981 + "," + 34.7373759815055
                    }
             }),
          }),
//===========

However, there should be a button to turn each layer on and off.
